The killer flu that’s been running around the prison on The Walking Dead for weeks now was particularly destructive during Episode 5, “Internment”. The sickness killed many red shirts, and even took the life of Dr. S. Glenn Rhee (Steven Yeun) and Sasha (Sonequa Martin-Green) looked like they might die as well, but thanks to some medicine and Hershel’s ability to rescue a breathing tube from a walker, they are both still with us.

Check out our gallery of additional photos from the episode to see Glenn and Sasha near death.
